GRAIN-DRILL ATTACHMENT.

SPECIIEICATION forming part of Letters Patent No. 266,325, dated October24, 1882.

Application filed February 18,18E'2. (No model.)

To all, whom it may concern.-

Beit known that I, PERRY HARRISON SMITH, a citizen of the United States,residing at Topeka, in the county of Shawnee and State of Kansas, haveinvented certain new and useful Improvements in Grain Drill Attachments;and Ido hereby declare the followingto beafull, clear, and exactdescription ot' the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accom panying drawings, and to letters or figures of referencemarked thereon, which form a part ot this specification.

This invention has for its object to furnish a roller attachment for thevarious kinds of seed-drills known as hoe-drills, whereby a separateroller will be provided to follow in the furrow formed by each lloe.

rlhe invention consists in arranging the rollers in pairs, the rollersof each pair being on opposite ends ot' an axle pivotedat its center, sothat it has a rocking or seesaw movement, whereby the two rolls readilyadjust themselves to an uneven surface.

ltconsists, further, in the arrangementof the several pairs of rolls, incombination with the frame, whereby each pair will have an independentvertieal movement or adjustment, so that it will readily pass overknolls or other obstructions.

lt consists, further, in having the drivers seat and the arms or leverswhich support the pairs of rolls so combined that the weight of thedriver is equally distributed over all the rolls.

lt consists, further, in the combination and arrangement of the severalparts hereinafter fully described.

ln the drawings, Figure lis a perspective of my attachment having aportion of the iirst roll removed. Fig. 2 is a side elevation of thesame; and Fig. 3 is a rear elevation, showing two pairs ot' the rollerswith their coupling devices.

This invention is intended to be attached to any ordinary drill. I havenot therefore shown a drill in the drawings, but show two hoes, A A, inposition in front ot the rolls, together with the t'urrows B B, openedby said hoes, and

,pair ofthe arms f f the wheels GG, composing one of the pairs supportedon their axle D and running in the furrows B.

e is a head-bar having alength about equal to the width of the ordinarydrill. It has fastened to it in suitable position two or morecoupling-arms, e. Only one ot' these coupling-arms is shown. rEhe othersare arranged at proper distances apart, and by them the head-bar iscoupled to the drill-carriage.

ff are two arms, which have their forward ends attached to the head-bare, and their opposite ends extended to the rear and provided withbearings adapted to slip onto the spindles D' D of the axle D and retainthe latter in proper place. The arms ff may be provided i'rom a singlebar of metal having its rear end bifurcated; or they may be separatebars, as shown. I have shown but a single as applied to one ot' theouter pairs ofrolls. armsare provided for each pair ot' rolls, andarranged in saine manner as the arms ff. rlhe axle D has its spindlesput through the bearings in the rear ends of the arms ff. rlhe hubs ofthe wheels c c ordinarily bear against the arms or against a washerfirst placed on the spindle against the ends oi' said arms. The axlesot' the two end pairs of rolls are pivoted at their centers to the lowerends of vertical standards g g, so that they will have an oscillating orseesaw movement, whereby either one ofthe rolls in said pairs may bedrawn over a clod, knoll, or other slight elevation without raising theother roll in said pair. rI he barsf j' are suitably connected at theirforward ends to the head-bar e, so as to permit this oscillatingmovement of the axles D. rlhe standards It will be understood that.

g g have their upper ends carried above the l peripheries of the rolls,and have placed on them a cross-beam, g', thelatter being secured sothat it will have a slight tilting movement on its fastenings. Theobject of this tilting movement is to permit the pair ot' rollers at oneend ofthe series to be lifted over any little kn0ll,'clod, or otherslight elevation without disturbing the position ot' the pair of rollersat the other end ot' the series, and also relieve the vertical standardfrom the strain which would result it' the cross-beam g were IOO fixedrigidly thereto. lhe standards g are supseveral parts hereinbetoredescribed.

ported by braces g2, which extend to and are made fast to the head-bare, as shown.

The device shown in the drawings has four pairs of rollers. The pairs EE are placed at the ends, and the pairs E E are arranged immediately inthe series, forming two sets ot' four rollers, each set being composedof one end pair and one intermediate pair. The end pair of rollers issupported as hereinbefore explained. The intermediate pair next the endhas its axle held in bearings in armsj'f, similar to the supporting ofthe axle of the end pair. To the middle of the axle of the nextintermediatepair the lowerend of a vertical bar, h, is pivoted. Theupper end ofthe bar L extends nearly to the cross-beam g, room beingleft for the vertical play hereinafter explained. The upper end ot' thebar 7o is pivoted to one end ot' a horizontal equalizing-bar, It. andthe other end ofthe equalizing-bar is pivoted near to the upper end ot'the standard g. The equalizing-bar h is preferably made in two piecesarranged parallel to each other, with their ends embracing the bar h andstandard g, as shown. When the intermediate pair or' rollers is thuscoupled to the end pair it will be seen that either pair can haveavertical movement independentlyof the other. rIhere is pivoted to thebar h, atthe middle point between the bargand the bark, thelower end ofthe supporthz, the upper end of which is carried upward through a slot,g3, in the cross-beam g. The end ot' the seat-bar K rests on the top ot'the support h2. I have described one set ot' two pairs of rollers. ltwill be seen that the construction, arrangev ment, and coupling togetherof both sets is exactly the same, and that the seat-bar rests on theends ofthe two uprights or supports h2, and that the pressure made byany weight placed on and at the middle of the bar K will be distributedequally to all t'ourof the pairs ot' rollers. This equal distribution iseffected by the peculiar construction and arrangement ofthe The driversseat K is fixed at the middle of the bar K; but in case more pressure beneeded on one set of four rollers than on the other the driver caneasily transfer his weight for the time being from the seat K along thebar K and over the rollers requiring increased pressure.

It will be seen that 'by the construction and arrangement ofthe severalparts, as hereinbcfore described, I secure an adjustmentofthe tworollers in each pair by means ot' the oscillating axle, a verticaladjustment 0f each pair ot' rollers independently ot' all the otherrollers, and an adjustment of one set of four rollers independentlyofthe other like set.

Having thus described my invention, what I claim, and desire to secureby Letters Patent,

l. The combination, with the frame for car. rying the rollers, of anaxle provided at its opposite ends'with spindles and pivoted at itsmiddle to the framing, and the two rollers placed on the spindles of theoscillating axle, and arranged in rear of and so that they will ltravelin the furrows formed by the shovels on the seeder-frame, substantiallyas set forth.

2. In a roller attachmentfor grain-drills, the combination, with theframe, of a series of rollers arranged in pairs, each pair being coupledto an adjacent pair, and having an independent vertical movement oradjustment, substantially as set forth.

3. The combination of the pair ot' rollers E, the standard g, cross-beamg', having slots g3, ofthe pair ot' rollers E', support h, equalizer' L,support h2, and seat-bar K, substantially as set forth.

In testimony whereof I aix my signature in presence ot' two witnesses.
